| Abstract(in English) | Oxygen reduction/evolution reactions on air electrodes in organic electrolyte solutions are very important as positive-electrode reactions of lithium air secondary batteries. However, there were many reports that the discharge capacities rapidly decreased after some cycles and the discharge/charge energy efficiency was very low due to large difference in discharge/charge voltages. We found RuO_2/carbon black showed superior high activities as electrocatalysts for air electrodes. In this study, the electrochemical properties were further improved by employing the suitable electrolyte solution. |
